, pointed out in the claims.

In the drawings Fig. 1 is an elevation, and

Figures 2 and 3 enlarged views of details,

indicated by near the middle of which a" frame B is mounted; with roll-su rtmg frames C and C at either end ig. 1). Frame B (Fig. 3) carries a shaft D upon one end of which a sprin blade E is mounted, inside the ring F. on the other end of the shaft D is a ar engaged by a worm in all of which like parts are like symbols.

A is a long base,

H on the shaft 0 a motor The motor also rotates a shaft K through the ears L. The outer end of shaft K (Fig. 1) drives the drum M through the worm and gear N.

The drums have wound thereon the aper web or strip S (Fig. 2), which is curve into a partial circle in order to pass through the ring F (Fig. 2). That thepaper strlilp is not a com lete circle inside the ring F ows it (the strip) to clear the frame, motor shaft, etc a The rotation of the motor not only sweeps the blade E around the inside of the curved paper strip, but the stri is advanced longitudinally simultaneous y at a relatively slow rate.

The ring F is insulated from the frame B, and is one of the terminals of an electric circuit, the other terminal being fastened to the frame B.

Now if the paper web or strip S is charged with a tassium iodide, silver bromide, ferricyani or other electrolytic substance the passing of an electric current therethrough from the blade E to the ring F will discolor,

or mark, the paper at that point.

" If then the blade E sweeps the surface of the curved paper strip while electric current signals are passing, the paper will be marked in different laces; and if these signals have an intelligible order, then a message is writ-. ten on the stri Of course, the continuous slow longitudinal movement of the paper stri limi te in duration only by the length of the stri (Ensideration of the subject discloses that there is a two-directional relative movement i. e., transverse and longitudinal, the transverse movement bein ,sa fifty to a hundred times per inch of t e ongitudinal movement.

As the subject'is now so widely understood, further detailed description is probably unnecessary.

What I claim, is-

1. The combination of a flexible strip,

permits a continuous record thereon,

between the strip and the marking member,

means for moving it longitudinally, means for transversely curving a portion of said strip to more than one hundred and eighty degrees of a circle, and means for laterally traversing the curved portion of said strip with a marking means a plurality of times perlongitudinal inch of said strip.

2. The combination of a flexible strip, means for moving it longitudinally, means for transversely curving a portion of said strip for more than three-fourths of a circle, means for laterally traversin the curved portion of said strip with an e ectric terminal contacting member a plurality of times per longitudinal inch of said strip.-

3. The combination of a flexible strip,

means for moving it longitudinally, means for transversely curving a portion of said strip into substantial] a circle, means for laterally traversing t e curved ortion of said strip with a contactin mem r a plurality of times per longitu mal inch of said strip.

4. The combination of a flexible strip means for transversely curving a portion of said strip into substantially a circle, means for repeatedly traversing the curved portion of said strip with a markin member in the same direction transverse 0 said strip, and means for producing movement between the marking member and the strip in a second direction longitudinal of the strip.

5. The combination of a receiving strip, means for producing longitudinal movement of said strip, means for repeatedly traversing said strip in a single transverse direction, said means comprising contact means moving at a constant rate and having a poriod'of contact with said strip agreater than half the period between travers s.

6. The combination of a base member, a

conducting ring mounted upon said base, a flexible strip havin a wi one-half the circum erence of said rin strip being curved transversely and t ed through said ring, and a contact member mounted to rotate within said ring and traverse said strip transversely.
